Effective restoration of dipole sum rules within the renormalized random-phase approximation

NUCLEAR STRUCTURE ^48,52,58Ca, ^90,96,110Zr; calculated isoscalar and isovector B(E1) distributions and strength functions, EWSR, centroid energies, S_PDR/S_GDR ratio. Fully self-consistent Hartree-Fock mean field with the renormalized random-phase approximation (RRPA) using the Skyrme interaction SLy5, and including the effects of ground-state correlations (GSC) beyond the RPA within the phRRPA for isoscalar (IS) and isovector (IV) dipole excitations.
